The Equilibrium Vapor Pressure for Benzene Is 94 $\Delta$ G = 0 And

The equilibrium vapor pressure for benzene is 94.4 mm Hg. When liquid benzene is in equilibrium with its vapor, we must have ________

A) ( $\Delta$ G = 0 and $\Delta$ G ^$\circ$ = 0.)
B) ( $\Delta$ G = 0 and $\Delta$ G ^$\circ$ > 0.) .
C) ( $\Delta$ G = 0 and $\Delta$ G ^$\circ$ < 0.)
D) ( $\Delta$ G = 0 and $\Delta$ G ^$\circ$ = 0.) .
E) ( $\Delta$ G < 0 and $\Delta$ G ^$\circ$ = 0.)
